Where is Cornelia on supersecret

If you go the Quarry and talk to Donny. And complete all of Donny's task, then he will give you something to find her. Then go to Cavern Falls on your map, walk throw the mountain/cliff. Then you will find yourself in a place called Behind the Falls, there Cornelia lays. *tip* Behind the Falls will never be found on your map since it's ''top secret'' :) so you must go the same way every time, to Cavern Falls on your map, throw the mountain/cliff, and in Cavern Falls. Remember that now!
